This year marks the twentieth anniversary of
horrifying events that are known to few, denied by some, and exploited for
political gain by others. Twenty years ago, on 16 March 1988, Iraqi bombers dropped chemical agents on the
town of Halabja
in Iraqi Kurdistan, killing several thousand civilians. The attack laid the
precedent for the tactical use of poison-gas against the Kurdish countryside on
the first day of every stage of a five-month counter-insurgency campaign that
followed shortly afterwards (this was codenamed Anfal, an Arabic word meaning "spoils of war"). These chemicals
killed a few hundred and achieved the intended effect of flushing terrified
villagers into the arms of Iraqi armed forces, who transported them to transit
centres, sorted them by age and sex, and carted off tens of thousands to
execution sites in the country's western deserts, far from Kurdistan, where
they have laid buried underneath a thin layer of sand until this day.

16 March is also the second anniversary of the
destruction of the Halabja monument by the townspeople
themselves, many of them surviving relatives. They were enraged by the habit of
the Kurdistan Regional Government (KRG; controlled, in that part of Kurdistan, by Jalal Talabani's Patriotic Union of Kurdistan) to shepherd
foreign dignitaries on a tour of the town's mass graves and memorials, while
doing little to rehabilitate the town itself and its people, many of whom
complain of debilitating delayed effects of mustard-gas.

To Kurds - especially to those who experienced
them and lost relatives - these events remain painfully alive. Very few families were unaffected, and in Germian,
the hilly hinterland of oil-rich Kirkuk,
entire families were wiped out as part of Saddam Hussein's Arabisation
campaign. The Kurds' drive for greater autonomy today, and independence down
the line when circumstances permit, predates Halabja and the Anfal, but these twin events gave the quest a
renewed urgency: the Kurds simply cannot trust a central Iraqi government not
to resort to similar tactics in the future. But they find themselves hemmed in
by neighbours - Turkey, Iran and Syria - that are hostile to their ambitions and
have the power to curb these; the recent Turkish incursion into northern Iraq
is only the latest such message being conveyed (see Hasan Turunc, "Turkey and the Kurds: the
politics of military action", 27 February 2008).

The United States has played a controversial role, having supported Saddam Hussein during the
Iran-Iraq war, then placing sanctions on Iraq that targeted the people rather
than the regime, subsequently removing the regime but failing to stabilise the
country, and establishing a tribunal whose structure it dictated and whose
mandate it restricted, lest embarrassing information be displayed about its
past policies. It should be no surprise that whatever goodwill the US may have
incurred by removing the regime, it has earned little trust from people who
have learned to live with a superpower's serial
betrayals, the Kurds included.

The facts of what happened are important. In
1988, the Iran-Iraq war was lurching toward an end after eight bloody
years, but on 14 March, a combined force of Iranian Pasdaran (Revolutionary Guards) and Iraqi Kurdish peshmerga made a surprise foray into Iraqi Kurdistan.
Crossing the border, they swooped down on the entire district of Halabja, which
incorporates several sub-districts, such as Khurmal, as well as resettlement
camps for villagers displaced in the village-destruction campaign, which had
escalated a year earlier with the appointment of Ali Hassan al-Majid, Saddam Hussein's cousin, as the overlord of
Iraqi Kurdistan. Militarily, the Iranian/Kurdish advance completely routed the
Iraqis. Many troops drowned in Darbandikhan lake; others managed to flee;
thousands were captured. The Kurdish rebel parties took control of Halabja and
Khurmal, while Iranian forces seized Iraqi defences on surrounding
hilltops.

On 15 March, Halabja was fully in the peshmergas' hands. Residents later recounted
that, while elated at being free from Iraqi oppression, they also had a sense
of foreboding. They were intimately familiar with the regime's brutal ways: a
year earlier, Iraqi security forces had razed one of Halabja's neighbourhoods
following street protests over the village-destruction campaign.

In the afternoon of 16 March, the Iraqi air
force launched a massive chemical strike against Halabja and Khurmal. Although no
accurate body count exists (survivors assisted by peshmerga and their Iranian allies hastily buried the dead in
makeshift mass graves), it is generally reported that 5,000 perished, mostly
from nerve-gas, the vast majority civilians. Many others were injured,
primarily by mustard-gas; they were evacuated to hospitals in Iran. The Pasdaran and peshmerga forces were equipped against chemical attacks and
therefore suffered only minor losses.

The blow at Halabja proved devastating to
Kurdish morale. The Kurdish insurgency crumbled overnight, and by 19 March the
regime was able to declare, in banner headlines, the collapse of the PUK's
headquarters in Jafati valley, northeast of Sulaimaniya. News of the Halabja
chemical strike spread like wildfire throughout Kurdistan, and the regime
capitalised on this by launching a methodical military campaign to dislodge not
only the peshmergas from the
countryside, but its civilian population as well, to never again have to deal
with a rural-based insurgency.

The
event manipulated

Until today, the Anfal campaign and Halabja gas-attack remain shrouded in ignorance
outside Kurdistan (see Human Rights Watch, "Genocide in Iraq: the Anfal
Campaign Against the Kurds", July 1993). The region was closed off to the world for so long and
its infrastructure has been so uninviting to foreign visitors that few have
made the trek to share with the Kurds their memories of suffering. The Kurds,
moreover, have been victims of their wartime alliance with Iran, whose
revolutionary Islamic regime has been ostracised ever since the fall of the
Shah in the late 1970s. Iraqi propaganda, backed by its ally the United States,
either denied what happened, played down the significance of these events, or
distorted them beyond recognition.

Within a week of the attack, the United States department of state, basing itself
on information provided by the Defence Intelligence Agency (DIA), claimed that Iran had also used poison gas in
Halabja. This information created enough confusion that the United Nations
Security Council delayed a resolution for two months and then condemned both
sides for using chemical weapons. The DIA's account was augmented two years
later by a former CIA analyst, Stephen Pelletiere, who suggested, using the
same DIA data, that the majority of Halabja casualties had been victims of Iran's use of
gas. Pelletiere has repeated his claim on numerous occasions, but has never
presented any evidence in addition to the vague speculations made by the DIA at
the time (see Stephen C Pelletiere, "A War Crime or an Act of War?", New
York Times, 31 January 2003).

This obfuscation has made it particularly
difficult for the Kurds to find international recognition for the tragedies of
the Anfal and Halabja. In Iraq itself,
many dismiss Kurdish claims as fantasies, while others cast these events as a
justified payback for the Kurdish insurgency ("the Kurds had it coming to
them"). The trial of Ali Hassan al-Majid and several senior military commanders
for crimes committed during the Anfal
campaign (resulting in the conviction of al-Majid and two colleagues in June 2007)
was a step toward fuller recognition of what took place; but controversies over
the tribunal's establishment, mandate and procedures have undermined its
credibility and thereby also the credibility of the evidence presented. A future
trial covering Halabja will suffer from the same deficiencies; moreover, the
main culprits, Saddam Hussein and Ali Hassan al-Majid (now appropriately
known as "Chemical Ali") will be long gone.

The
past appropriated

In January 2008, the Kurdistan Regional
Government organised its first major event commemorating the Anfal and Halabja. Both events are inextricably linked, the chemical attack serving as a powerful demonstration effect in suppressing the Kurdish
insurgency. Further commemorative and forward-looking events are planned. These are welcome, as
knowledge and broad acknowledgment of these atrocities is long overdue. (The Anfal was ruled to constitute genocide
by a Dutch court that in 2005 convicted a businessman who had provided the Iraqi regime with the
chemical precursors it needed to manufacture lethal agents).

For the KRG, commemorating the Anfal/Halabja serves a political agenda
in support of greater Kurdish autonomy in Iraq. For the many survivors,
though, the question is whether they will see any benefit from greater
publicity concerning these ghastly events, about which they had no
foreknowledge, over which they exercised no control, and in the aftermath of
which they have been neglected, except as passive victims displayed on stage at
political occasions.
